20080308357 | Permanently-installed wheel chair lift with height control - A height control mechanism for a lift device includes an elongated rail and an actuator slidingly mounted thereto. The actuator is biased toward a first end of the rail, and a proximity sensor is mounted proximate the second end of the rail. A cable pulls the actuator toward the second end of the rail as the lift device is elevated. When the proximity sensor detects the presence of the actuator, a signal is generated to halt further elevation. The position of the proximity sensor along the rail can be adjusted to set the maximum height of the lift device. A second proximity sensor, responsive to the presence of the actuator, can also be secured to the rail to generate a signal indicating that the lift device has been elevated off of the ground by a short distance. | 12-18-2008 |

While the invention is in the “lowered” position. the user can move their MAD atop the platform contained in the present invention. While atop the platform, the user can activate the controls and cause the platform to be moved into the “raised” position. The “raised” position moves the user and their MAD upwards and towards the top step of entrance of the facility. The user can then mobilize their MAD and egress off the platform into the facility. If the user desires to exit the facility, the user then reverses the process and enters onto the platform when it is in the “raised” position. The user, while atop the platform, then lowers the platform to its “lowered” position and is able to egress off of the platform. The present invention accomplishes the “raising” and “lifting” functions while utilizing a minimal footprint and impact on existing groundscape. Additionally, the present invention, by design can be easily relocated if the user desires to do so. | 05-15-2014 |
